Lymphatic drainage of the ovary is primarily to which group of lymph nodes?

• A Superficial inguinal nodes
• B Para-aortic nodes around the origin of the renal arteries ✓
• C Internal iliac nodes
• D External iliac nodes

Explanation

The ovaries descend from the posterior abdominal wall at the level of the L1-L2 vertebrae, carrying their lymphatics along the ovarian vessels to the para-aortic nodes at the level of the renal vessels. This embryological descent also explains referred ovarian pain to the loin. The inguinal nodes drain the vulva and lower vagina, not the ovary, which kills option A.
